io.lettuce.core.output.CommandOutput<K,V,List<ReplayOutput.Signal>>

io.lettuce.core.output.ReplayOutput<K,V>

public class ReplayOutput<K,V>
extends CommandOutput<K,V,List<ReplayOutput.Signal>>

Replayable CommandOutput capturing output signals to replay these on a target CommandOutput. Replay is useful when the response requires inspection prior to dispatching the actual output to a command target.

ReplayOutput

public ReplayOutput()

Initialize a new instance that encodes and decodes keys and values using the supplied codec.

Method Details

set

public void set(ByteBuffer bytes)

Description copied from class: CommandOutput

Update the command output with a sequence of bytes, or null. Concrete CommandOutput implementations must override this method to decode bulk/bytes response values.

Overrides:

set in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

bytes - The command output, or null.

set

public void set(long integer)

Description copied from class: CommandOutput

Update the command output with a 64-bit signed integer. Concrete CommandOutput implementations must override this method to decode number (integer) response values.

Overrides:

set in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

integer - The command output.

setError

public void setError(ByteBuffer error)

Description copied from class: CommandOutput

Set command output to an error message from the server.

Overrides:

setError in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

error - Error message.

setError

public void setError(String error)

Description copied from class: CommandOutput

Set command output to an error message from the client.

Overrides:

setError in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

error - Error message.

complete

public void complete(int depth)

Description copied from class: CommandOutput

Mark the command output complete.

Overrides:

complete in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

depth - Remaining depth of output queue.

multi

public void multi(int count)

Description copied from class: CommandOutput

Mark the beginning of a multi sequence (array).

Overrides:

multi in class CommandOutput<K,V,List<ReplayOutput.Signal>>

Parameters:

count - expected number of elements in this multi sequence.

replay

public void replay(CommandOutput<?,?,?> target)

Replay all captured signals on a CommandOutput.

Parameters:

target - the target CommandOutput.
